Rotary device with impeller, rotor, stator, bearing, and fan
A newly granted patent (Publication Number: US12009731B2) discloses a rotary device designed with innovative features to enhance efficiency and performance. The device comprises a housing with an impeller, rotor, stator, and bearing, along with a fan mounted externally to introduce and release external air. The unique configuration allows for the external air to be heated while traveling through a cooling flow path within the housing before being released back outside. The inlet and outlet of the housing are strategically positioned to facilitate the flow of air in specific directions, optimizing the cooling process. Additionally, the device includes heat dissipation fins and a coating layer on the rotor for improved lubrication, further enhancing its operational capabilities.
Furthermore, the patent details various embodiments and methods of operating the rotary device, including scenarios where the fan is positioned at the inlet or outlet to control the direction of airflow. By driving the fan in specific directions, the external air is efficiently introduced into the housing, heated, and released back outside, contributing to the overall effectiveness of the device. The inclusion of multiple cooling flow paths and the proximity of the inlet to the bearing for heat transfer highlight the innovative design aspects aimed at maximizing performance and minimizing friction. Overall, the patented rotary device showcases a sophisticated and well-thought-out engineering solution for efficient air cooling in rotary applications.
